Abstract

This paper presents qualitative models of interactions between two populations in biological communities. Negative and positive interactions like competition, predation and symbiosis are considered determinant factors in the structure of communities and are important topics in ecological theory and practice. Qualitative simulations can be used for representing such ecological knowledge in interactive learning environments. Using the qualitative theory about population dynamics already implemented in GARP, we created qualitative simulation models to support predictions about some of the most common behaviours of two interacting populations. Modelling assumptions are explicitly represented and therefore can be analysed by students and modellers. We briefly discuss how these models can be organised to create interesting learning routes.
